you need to make it really cold and then it turns into nitrogen, and the other way is you can melt the ice and it will evaporate becuase you are just changing the change of state of matter and thats a physical change, so even if you melt it it will be the same.
The change of ice to a liquid is melting; the direct change of ice to a gas is sublimation.

Yup
When ice changes directly into a gas without becoming a liquid the process is called sublimation.
The change of phase or state is when a liquid, gas, or solid change its form! liquid can turn into a solid (ice) or a gas (steam). Gas can turn into a liquid (water).But there are some exceptions to this rule , such as dry ice. Dry ice turns directly into a gas.
The process of dry ice sublimating, or turning directly from a solid to a gas, is a physical change. No new substances are formed, just a change in the physical state of the dry ice from solid to gas.
Yes. Dry ice, for example.

Yes
Correct, any phase change is considered to be a physical change.
These are phase changes, ice melts into water and water evaporates into a gas.
let it melt then evaporate it:)
